Exactly.. It's a fine line to raise a dog to be not dependent, but not independant either.. Does that make sense?
Too dependant and you get anxiety disorders, too independent and you have no control..
There's a post on the yorkie board right now where someone is asking about potty training.. Someone told them to hold the dog ALL the time when he's not outside.. When he goes outside, let him play for a few minutes and then hold him again for the couple of hours until he needs to go out.. It didn't sound like they meant on a leash, but actually in your arms.. Aside from being deathly irritating for the owner, that dog would have countless seperation anxiety problems when the owner so much as went to get groceries..
And then if the dog is never in your company while you're sleeping, eating, working, watching tv, he'll never understand proper behaviour in a human dominant world..
heh.. the problems we put ourselves through as dog owners 
And when you think about it, even farm animals are inside at least some of the time.. And then you get my aunt, who's dog's official breed is Falabella, a miniature horse.. She's housetrained just like a dog, walks on a leash and halter just like a dog, fetches things, sleeps on the couch with them when they're watching tv.. The house is a split level so that the largest flight of stairs is 5 high, and when they built the house they had ramps put in beside all the stairs for her..
If they can manage to live with a horse in the house, anyone should be able to manage living with a dog..
